“The performance reportedly used the same technology that enabled Mariah Carey to perform a concert in five cities simultaneously. Executing the Carey illusion relied on both modern day techniques and an old magician’s trick dating back to the 19th Century. First, a video was composed by New York SFX company MPC using a mixture of live footage, wire-framing, and CGI. This was then fed into Musion’s holographic technology, which projects the image onto a special foil. The foil is based on principles set out in the old magician’s illusion Pepper’s Ghost, which trick audiences into thinking they’re viewing a person or object rather than a simple reflection. By using a lightweight foil which mimics the properties of semi-transparent glass, Musion is able to extend the concept’s scale without limiting the efficacy of the illusion. The results, as you can see in the video below, are pretty spectacular.”

Dr. Dre, Snoop, Wiz, Tony Yayo, Kurupt, Kendrick Lamar (check the vid after the jump), Eminem, 50 Cent, and Warren G all made appearances at the show. The fans were a motley crew that grew up on these rapper’s music; they sung along with every word to every song. I can imagine that the feeling at this show was incredible…
